| 摘要 |
The present invention provides an input cueing system and method that allows the user to manually draw an image, input text, interface and gesture on an input surface, which is then brought into a computer such that the visual output from the computer is combined in an overlapping manner with the visual imagery of the user's hands, and then shown on a display. Located above the drawing surface is an image capturing device that captures live video images of the user's hands or other objects placed on the drawing surface. One or more reflectors and/or image repeating devices are disposed of between the input surface and the image capturing device to effectively reduce the height and/or focal length so that the visual image is properly aligned and oriented to provide a real ‘live’ view of the users hands and/or action on the display. In one embodiment, the system is used with a desktop computer and a display. In further embodiments, the system is incorporated into a laptop computer, a slate, a PDA, or a cellular telephone with a built-in display. In various embodiments, a combiner module is used to combine the visual action occurring on and/or about the input surface by an image capturing device with the visual output from a computer or computing device, so that the resulting combined visual imagery may be simultaneously transmitted and on a display, with the users hands, fingers and/or tools shown in a semi-transparent and/or opaque manner. |

1. An input cueing system for simultaneously viewing in real time the image of a user's hands or fingers positioned over the input device that overlays a virtual input image, the system comprising:
an electronic device that includes an electronic controller; a processing device connected to the electronic controller, and a display connected to the electronic device and positioned in the user's field of view; an input device coupled to the electronic controller, the input device includes an input area in which the user moves at least one hand or at least one finger that creates an input area signal that is transmitted to the electronic controller; a software program configured to produces the virtual input image presentational on the display that uses the input area signal from the input device; an image capturing device coupled to the electronic device disposed above and aimed at the input area that produces a realistic real time image of the user's hand or finger in the input area, the image capturing device includes a primary mirror disposed below the direct field of view of the display thereby providing the user an unobstructed view of the display and above the input area and aimed to capture and reflect the image of or about the input area, a secondary mirror located below the direct field of view and aimed to reflect the image of the input area from the primary mirror, and a camera located about the input area and below the direct field of view of the display thereby providing the user an unobstructed view of the display, wherein the camera is aimed at the secondary mirror to receive the reflected image of the input area from the primary mirror and, a combiner coupled to the electronic device configured to simultaneously present an overlying image of the user's hands or finger on the display that is aligned and registered over the virtual input image that allows the user to accurately and expediently input information into the electronic device.
